IMPROVEMENT IN CHECK ROW ATTACHMENTS FOR PLANTERS.

Specification forming part of Letters Patent No. 156.085, dated October20, 1874; application filed September 5, 1874.

To all whom it may concern:

Be it known that I, LYSANDER L. HAWORTH, of London, in the county ofMadison and State of Ohio, have invented a new and useful Improvement inCheck-Row Attachments for Planters, of which the following is aspecification:

Figure 1 is a top view of my improved attachment. Fig. 2 is a detailcrosssection of the same taken through the line w as, Fig. 1. Fig. 3 isa detail perspective view of a portion of the same.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved attachment,designed especially for one-horse planters to enable them to plant thehills in accurate check-row, and which shall be simple in constructionand conveniently applied to the planter.

The invention consists in the combination of the weighted arm and theguard-arm with the slotted arm, through which a knotted cord passes, andwith the shaft that operates the dropping-slide, as hereinafter fullydescribed.

A represents a cross board or bar, which is designed to be secured tothe frame of the planter, and to the upper side of the end parts ofwhich are pivoted two pulleys, B, around which passes the cord 0, whichis stretched across the field, the ends of which are secured to theground by stakes or other convenient means, and which is provided withknobs or knots 0 at the required distance apart of the hills. D is ashaft placed a little in front of the board or bar A, and which works inand is supported by brackets E, at tached to said board. To the ends ofthe shaft D are attached arms F, which are slotted longitudinally toreceive the rope or cord 0, said slots being made of such a size thatthe cord 0 can slide through freely, but not the knots 0, so that aseach knot c strikes the slotted arm L it turns the said'arm F to therearward until it can slip through the outer part of said slot. As eachknot c of the cord O slips through the arm F, the said arm is againcarried forward by the weighted arm G, also attached to the end of theshaft D. To the ends of the shaft D are attached the guardarms H, whichproject a little in front of the slotted arms F, and the outer ends ofwhich are bent inward across the outer ends of the slotted arms F, asshown in Figs. 1, 2, and 3, so as to prevent the cord G from getting outof the slot of said arms F as the knots c slip through them. To themiddle part of the shaft D is attached an arm, I, with which thedropping slide and valve of the planter are designed to be connected. Tothe shaft D is also attached a stop-arm, J, which strikes against thelower side of the board or bar A, and prevents the slotted arm F frombeing carried so far forward by the weighted arm G as to pass oif thecord 0.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of the weighted arm G and theguard-arm H with the slotted arm F, through which the knotted cord orrope passes, and with the shaft D, substantially as herein shown anddescribed.
